Okay, so we've got liquid butane at c4h10.
00:06
That's liquid.
00:08
And it's going to be burned to produce co2 and h2o.
00:14
So that means combustion, burning, always requires oxygen.
00:20
So we know there's going to be oxygen and it's going to be gaseous.
00:26
And then we're going to get co2, which is also going to be a gas, and h2, which is also going to be a gas.
00:34
So the reason why i know these are gas is because it requires a certain input of energy to burn stuff, right? at that high temperature, carbon dioxide, and water are gaseous.
00:52
So now we got to use whole number coefficients.
00:55
Okay, so our first step is always going to be to balance the carbons.
00:59
Carbons come first.
01:01
Oxidens come last because they're by themselves.
01:04
So then you can do whatever you want and then fix oxygen at the end.
01:10
That leaves hydrogen for the middle.
01:15
Okay.
01:16
So let's look at this.
01:17
We have four carbons on the left.
01:19
We need the law of conservation of mass.
01:22
So four on the left means four on the right.
01:25
So we put a nice little four right there...
